Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides teeth for discharging hair dye, etc. that can move forward and backward into the space of a case that forms a gap for inserting hair, etc., and discharge the hair dye at the same time as the teeth advance This invention relates to a hair dyeing device designed to discharge such substances.

The present invention provides a hair dyeing tool that prevents harmful hair dye from adhering to the scalp and the like, and which can dye hair in one operation.

According to the present invention, teeth capable of discharging hair dye, etc. are provided in a case formed with a gap for inserting hair, etc., and teeth capable of discharging hair dye, etc. are movably provided in the gap, and the teeth are biased to open and mutually A pair of variable volume liquid containers are fitted with the teeth that mesh with the case, and are slidably fitted into the case, and by pressing the pair of liquid containers together, the volume of the liquid container changes at the same time as the teeth advance. This hair dyeing device is characterized in that the hair dyeing solution is discharged by reducing the size of the hair dyeing device.

Next, an embodiment of the hair dyeing device according to the present invention will be described based on the drawings.

The figure shows a pair of liquid containers 3, 3a housed in a pair of removable cases 2, 2a that form a desired spacing 1, 1a, 1b (for example, 2 cm width) to hold a certain amount of hair, etc. The configuration is shown.

One of the cases 2 and 2a is approximately crescent-shaped, and both ends are cut out (the bottom of the cutout has a deep and narrow shape), and when the two are combined, the notch forms a space 1 and 1a for hair guidance. In addition, a gap 1b serving as a hair passage is formed in the center.

The intervals 1 and 1a are wedge-shaped and narrow so that the hair can be easily gathered and gathered.

The cases 2 and 2a are configured to be disassembled freely, and a longitudinal guide groove (dovetail groove) 4 is formed on the side of the upper surface of the case 2.
On the other hand, a rail (T
5 are provided, and these are connected by sliding fit.

The cases 2 and 2a have guide grooves (not shown in the drawings, but
A dovetail groove shape is preferred. ) 6 are provided.

A through hole 8 for a push button and a through hole 9 for a stopper of the liquid containers 3, 3a, which will be described later, are bored in the back surface of the cases 2, 2a so as to penetrate into the chambers 7, 7a. Room 7, 7a
The bottom surface is of a somewhat concave configuration. In the chambers 7 and 7a of the cases 2 and 2a, there are liquid containers 3 and 3, respectively.
A is stored so that it can move forward and backward stably.

The liquid containers 3, 3a are connected to the guide grooves 6 of the chambers 7, 7a.
A rail (T-shaped rail) 11 is provided at a relative position so as to fit into the case 2, 2a, and the liquid containers 3, 3a themselves slide within the chambers 7, 7a of the cases 2, 2a and are fitted so that they can move forward and backward.

The bottom surfaces of the cases 2 and 2a are slightly inclined or curved so that both ends are raised to reduce contact with the skin surface.

The liquid containers 3, 3a are provided with a liquid inlet and a sealing lid 12 on the upper surface, a horizontal bellows-like protrusion 13 on the upper part, teeth 14 for discharging the hair dye etc. on the lower part, and on the back side. The container is equipped with a push button 15 and a small bellows-shaped protrusion 16, and is a hollow container with a substantially U-shaped side surface.

The liquid containers 3, 3a are provided with bellows-like protrusions 13, so their volumes are variable.

An air hole 17 is formed on the front surface of the bellows-like protrusion 13 so that a rubber plate 13a can be attached to the air hole 17 to seal it as tightly as possible.

This air hole 17 can be opened by narrowly pressing the push button 15 of the pair of liquid containers 3, 3a.
3a advances and the front surfaces of both bellows-like protrusions 13 contact and contract to close the air hole 17, and at the same time, the volume of the liquid containers 3, 3a is reduced, the pressure inside increases, and the dyed hair is removed from the teeth 14. It is an air intake that restores volume after draining the liquid. Therefore, the air hole 17 is
It is preferable that the positions of each liquid container 3, 3a are slightly shifted. Further, if the tooth 14 itself is configured to take in air after discharging the liquid, the air hole 17 can be omitted.

Teeth 14 are arranged in a row in a comb shape at the lower part of the liquid containers 3, 3a.

The length of the teeth 14 is such that the teeth 14 are normally accommodated in the chambers 7, 7a of the cases 2, 2a.

The teeth 14 provided on each liquid container 3, 3a are configured to mesh with each other so that the hair dye can be evenly applied to the roots of the hair. The degree of meshing is related to the degree of pressing of the push button 15.

These teeth 14 are configured to ooze out the hair dye when the volume of the liquid containers 3, 3a is reduced and the pressure is increased.

For example, a bundle of resin fibers, a material with a large number of pores perforated, a material covered with cloth, a material made of a permeable material, etc., which are relatively hard and can be molded into a tooth shape are selected.

Since this tooth 14 is the most important part and is frequently used, it is made as a separate part 14a, for example, as in the embodiment shown in FIG.
It may be configured to fit into the main body. In this case, the teeth 14 excluding the tooth forms forming the sides of the containers 3, 3a
The part is a separate part.

That is, only the tooth 14 portion (excluding both side end surfaces) inside the containers 3, 3a is molded.

By configuring the teeth 14 as separate parts, the degree of liquid exudation from the teeth 14 can be set to an arbitrary degree, and hair dye liquids of various concentrations can be used. As described above, the push button 15 and small bellows-like protrusions 16 are provided on the back surface of the liquid containers 3, 3a. The bellows-shaped small protrusion 16 is normally shortened, and when it is extended by pressing the push button 15, it acts to contract and close the liquid container 3,
It is provided to urge the opening 3a to open.

The push buttons 15 penetrate through the through holes 8 of the cases 2 and 2a and protrude outside.

The side concave portion of the push button 15 has a guiding shape that works together with the convex portion of the through hole 8 to enhance stability. The push button 15 has an appropriate shape (such as a concave shape where the center part can be easily touched) so that the push button 15 can be easily pressed by the fingers, and the degree of the protrusion is determined according to the width of the gap 1b.

The rear end of the bellows-shaped small protrusion 16 is fixed in the through hole 9 with a stopper 18 having a large diameter head.

When the push button 15 is pressed tightly to advance the liquid containers 3, 3a, the small protrusion 16 extends, but the stopper 18
Since the rear ends are fixed to the back surfaces of the cases 2, 2a, when the push button 15 is released, the liquid containers 3, 3a are energized to return to their original positions.

The force exerted by the bellows-shaped small protrusion 16 is applied to the liquid container 3,
Since it does not affect the volume change of 3a, other biasing means (such as a spring) may be used instead.

Incidentally, the liquid containers 3 and 3a are made of transparent synthetic resin so that the liquid inside can be seen, and although not shown, the cases 2 and 2a are also made of transparent material or transparent so that the amount of liquid can be seen. Preferably, a window is formed.

In addition, the bottom of the liquid containers 3, 3a is connected to the cases 2, 2a.
The guide groove 6 and the rail 11 can also be configured to be slightly inclined as shown by the dashed line in FIG.

This is effective because the teeth 14 get closer to the roots of the hair.

Furthermore, a partition plate 20 is provided inside the liquid containers 3, 3a.
are set up consecutively.

These are provided at intervals according to the position of the teeth 14, and are designed to prevent the liquid from being concentrated to one side and only air being exhausted when the device body is used next to the scalp. It is what was done.

Even if you tilt your head and try to use the appliance horizontally, even if you use it at a slight angle, fluid will drain evenly from all teeth.

If it is assumed that the main body of the device is used vertically, it is easy to change the design by attaching horizontal short blades to the partition plate 20, since the liquid can be trapped in that part.

Another embodiment shown in FIG.
between the upper end bellows-like protrusion 13 of the cases 2, 2.
A hanging piece 19 is interposed from the upper surface of a.

This embodiment shows a configuration in which the pressing forces on the liquid containers 3 and 3a are made independent of each other, making it easier to equalize the degree of protrusion of the teeth 14 by controlling the fingers.

Between this hanging piece 19 and the bellows-like protrusion 13,
If the air hole 17 is bored in the front surface, a slight gap will be formed.

Next, the operation and method of using the hair dyeing device according to the present invention will be explained.

First, a certain width of hair or the like is inserted into the space 1 between the cases 2 and 2a, and the instrument body is advanced along the scalp.

Then, the hair is gathered together according to the deep and narrow interval 1, and bends and enters the intermediate interval 1b between the cases 2 and 2a.

Even if the hair is bent, the roots of the hair stand up by their nature.

The hair that has entered interval 1b is regulated by interval 1, so it does not fall apart.

When a certain amount of hair is located in the interval 1b, the push button 15 is pressed with a finger motion.

Then, the bellows-like protrusions 13 of the liquid containers 3 and 3a abut each other (or abut against the hanging pieces), closing the air hole 17 and reducing the size.

Therefore, the volume of the liquid containers 3, 3a becomes smaller, the internal pressure increases, and the liquid L is discharged from the teeth 14, and at the same time, the teeth 14 move forward and pinch the roots of the hair and apply the hair dye. I will let you do it.

In this case, the bottom of cases 2 and 2a is slightly thick and curved, so the liquid will not stick to the scalp, and a certain amount of liquid will be discharged for a certain amount of hair, so there will be no need to apply too much. There will be no.

Then, by releasing the push button and moving the case along the scalp in order to dye the hair, the hair dye solution can be evenly applied to the roots of a certain width of hair.

When the push button 15 is released, the liquid containers 3, 3a are energized in the opening direction, so they automatically open and take in air from the air holes 17 (or the teeth 14 themselves).

The liquid containers 3, 3a are restored to their original volumes and enter the chambers 7, 7a of the cases 2, 2a.

Even if the liquid inside the containers 3, 3a whose volume has been restored is reduced, the liquid will be discharged with the same air pressure due to pressure, and a constant amount of liquid will always be discharged.

As described above, the hair dyeing device according to the present invention has the extremely practical effect of being able to easily apply a certain amount of hair dye solution to the skin without causing it to adhere to the skin in one operation.

Further, since the equipment itself can be disassembled, it is convenient for cleaning and is clean, and the hands of the hair dyeing technician are not soiled.

The present invention is an excellent invention that can be used not only as a scalp hair dyeing device, but also for, for example, animal hair dyeing or partial dyeing of various textile products.
